Application filed Au ust 7, 1924, Serial No. 730,682.

To aZZ whom it may concern: p a I Be it known that I, EDWARD Nonssnn, acitizen of the United States, residin at Denver, in the county of Denverand btate of Colorado, have invented certain new and; usefulImprovements in a Saw Set, of which the following is a specification.

My invention relates to improvements, in saw-sets.

An important object of the invention is to provide a saw-set which isadapted to set a plurality of teeth at the same time, the alternateteeth being set in opposite directions, whereby the complete setting of.the teeth is effected by one operation.

A further object of the invention is to provide a device of theabove-mentioned character, so constructed that the setting operation isvisible. I

A further object 'of the invention is to providea saw-set havingdetachable setting teeth, whereby the teeth may be employed forsaws ofdifferent sizes, and also the number of teeth set at. the same time maybe varied. i T j A, further object of the invention is to provide adevice of. the above-mentioned character, having simple andreliablemeans for holdingthe sameagainst slipping movement upon the sawduring the setting operationf A further object of the invention is toprovide a saw-set having adjustable means to regulate the angular extentof the setting.

A further object of the invention is to provide an adjustable gage,whereby the saw-set may be quickly and conveniently shiftedthe properdistance after each setting operation. I I

Other objects and advantages of the invention will be apparent duringthe course of'the following description.

In the accompanying drawings forming a part of this specification, andin which like numerals are employed to designate like parts throughoutthe same.

Figure 1 is a plan view of a saw-set and gage embodying my inventlon;

Fig-2 is aside elevation of the same Fig. 3 is an edge elevation of thesame;

Fig. 4 is a similarvie'w, with parts in central vertical section, takenon line; 4-4 of Fig. 1;

Fig. 5 is a vertical sectio 5--5 of Fig. 4. 1

taken on line ,Fig. 6 is a detail horizontal section taken on. line 6-6of Fig. 3;

F ig. 7 is a central longitudinal vertical sectionthrough the adjustablegage;

Fig. 8 is a transverse section taken on line 8+-8 of Fig. 7; and F 1g. 9is a perspective View of one of the setting teeth carrying plates.

In the drawings, wherein for the purpose of illustration is shown apreferred embodiment of my invention, the numeral 10 designates a lowerhandle, having its forward end provided with afork 11, forming arelatively large opening 12. This forkis provided with upstandingknuckles13, from which, depend a forward jaw 14, rigidlysecured'thereto. Arranged above the lower handle 10 is an upper handle15, provided at its forward end with a fork 16 carrying knuckles17 Theknuckles 17 are arranged within the knuckles 13, and are pivotallyconnected therewith by pins 18 or the like. The fork 16 provides a largeopening, lead ing into the opening 12. epending from the knuckles 17 andformed integral therewith is a rear jaw 19, disposed opposite theforward jaw 14. Formed integral with the lower ends of the jaws l4 and19, are inwardly facing sockets 20, receiving resilient clamps 21,formed of rubber or like material. These clamps are adjusted by means ofscrews 22, engaging within screw-threaded openings 28. The extent ofinward movement of the handles 10 and 15 is regulated by an adjustableset-screw 24, engaging within a screw-threaded opening 25, and

contacting with the upper lever 15, as

shown.

Formed upon the inner faces 14 and 19 are recesses 24 (see moreparticularly Fig. 6) for the reception of setting teeth carrying plates25, which are detachably held within these. recesses by means of screws26 or the like. The plates 25 are provided at their opposite ends withsetting teeth 27. As more clearly shown in Fig. 1, the teeth on oneplate are arranged to enter the spaces'between theteeth of the oppositeplate, and

these two sets of teeth carried by the upper ends of the plates will seta plurality of saw teeth, the alternate saw teeth being set in oppositedirections. It is obvious that the plates 25 may be readily removed fromwithin the recesses, and inverted, whereby the setting teeth at theiropposite ends may be employed. It is also obvious that the plates may beentirely removed and other plates substituted therefor, having'settingteeth of different sizes or character, depending upon the size andcharacter of the saw teeth to be set.

I provide an adjustable gage, to regulate the extent of movement of thesaw-set, at the end of each setting operation. This gage embodies a bodyportion or block 28, whieh maybe formed of wood or the like, andprovided in its lower'e'dge'wi'th a groove 29, to receive the teeth ofthe saw 30. A wear plate'Sl, formed of metal or-the like, is preferablylocated at one end of the slot 29, and a vertical metal plate 32 issecured tothe opposite end of thebody portion or block 28, by screws 83or the'like. This metal plate serves as'a stop, and has a beveledtooth-8 f, extending downwardly below the top wall of the slot, andengaging behind the saw teeth.. The stop plate has an opening 35,loosely receiving the screwthreaded portion of a rod 36, having a Fdownwardly bent end 37, but has no screwthreaded engagement with thisportion, which is free to reciprocate therein. A nut 58 is carried bythe screw-threaded portion of the rod 36, within a recess 89, and anadjustable thumb nut '4i0 engages the screwthreaded portion oftherod,outwardly of thestop plate '32. The downwardly bent end 87 is adaptedfor insertion within an opening formed in the ear 41, rigidly secured tothe fork 11, as shown.

Inthe use ofthe device, the thumb-nut 40 is first adjusted, foreffecting a proper distance between it and the stop plate 82, dependingupon the distance occupied by thenuinber of'saw teeth which are set atonetime. This having been properly'deterniined,1the "body portion orblock 28 is arranged upon the saw teeth, with the tooth 34. between apair of selected teeth. The saw-setmay now be moved the maximum distancefrom the body portion 28, spaced upon thesaw, with the teeth 27'engaging the saw teeth to be set. The handles 10 and15 are now broughttogether, by the operator squeezing them in his hand. The resilientelements 21 'first'grip the saw, so that the set cannot slip thereon,and subsequently the teeth 27 set the saw teeth. lVhile the saw set isclamped to the saw, the operator may shift the block 28 toward thesaw-set, until the stop platev 82 contacts with the nut-t(), and canhold this block to the teeth. The saw-set may be released from the teethof thesaw, and then shifted from the block 28, until the nut 38 contactswith the stop plate 82, at'which time the sawset 'will be in the properposition to set the nextset of teeth. This operation may continue, as'is obvious.

An important featureofthe invention is the provision of the openings inthe forks of the handle, which permit of the setting operation beingvisible at all times.

It is to be understood that the form of my invention herewith shown anddescribed is to be. taken as a preferred example of the same, and thatvarious changes in the shape, size, and arrangement of parts may beresorted towithout departing from the spirit of my invention or thescope of the subjoined claims.

Having thus what I claim is:
